Background

The magic cube comprises a central shaft and a plurality of magic cubes arranged on the central shaft. The center shaft comprises a core and a plurality of connecting rods which are arranged on the core at intervals. Generally, the cube blocks include corner blocks, and center blocks (there are no center blocks in some low-order cubes). The magic cube blocks are spliced to form a plurality of magic cube layers and a plurality of magic aspects. For high-order magic cubes (such as a positive fourth-order magic cube, a positive fifth-order magic cube or a three-order pyramid magic cube), at least two magic cube layers are arranged on the connecting rod in a penetrating manner, and the at least two magic cube layers can rotate around the axial direction of the connecting rod.

The intelligent magic cube is a novel electronic magic cube which senses the rotation of a magic cube layer and the real-time state of the magic cube through a sensor and processes, stores and transmits information such as the real-time state and the rotation to external equipment. The intelligent center shaft of the intelligent magic cube is the core part of the intelligent magic cube, and can detect the rotation signal of each magic cube layer of the magic cube so as to acquire the integral real-time state of the magic cube, and then can communicate with electronic equipment outside the magic cube in real time.

Example 1

Fig. 1 shows a sensor (hereinafter referred to as sensor) for use in an intelligent puzzle. Fig. 2 is an axial cross-sectional view of the sensor depicted in fig. 1. Fig. 3 is an exploded view of the sensor depicted in fig. 1. Referring to fig. 1 to 3, the sensor 10 includes a stator 100, a first rotor 210, and a second rotor 220. Referring to fig. 5, 9 and 11, the stator 100 is for being fixedly disposed on the intelligent magic cube. The first rotor 210 is configured to rotate in synchronization with the first cube layer 41 of the intelligent cube such that the stator 100 or the first rotor 210 can output a rotation signal of the first cube layer 41 when the first rotor 210 rotates with the first cube layer 41 relative to the stator 100. For example, the stator 100 or the first rotor 210 can output a rotation signal of the first magic cube layer 41 according to the relative rotation amount of the stator 100 and the first rotor 210. The second rotor 220 is configured to rotate in synchronization with the second cube layer 42 of the intelligent cube such that the stator 100 or the second rotor 220 can output a rotation signal of the second cube layer 42 when the second rotor 220 rotates with the second cube layer 42 relative to the stator 100.

The sensor 10 can be applied to intelligent magic cubes, and the stator 100 is fixedly arranged and does not rotate along with the rotation of the magic cube layer. The first rotor 210 can rotate with the first cube layer 41 relative to the stator 100, and the sensor 10 can output a rotation signal of the first cube layer 41 according to the relative rotation between the first rotor 210 and the stator 100. The second rotor 220 can rotate with the second cube layer 42 relative to the stator 100, and the sensor 10 can output a rotation signal of the second cube layer 42 according to the relative rotation between the second rotor 220 and the stator 100. Thus, the sensor 10 utilizes the structure of one stator and two rotors to realize the detection of the rotation signals of two magic cube layers of the intelligent magic cube, so that the next step of obtaining the state signals of the intelligent magic cube is facilitated, and the intelligent magic cube is realized.

The stator 100 is fixedly arranged on the intelligent magic cube, and specifically, the designator 100 is fixedly arranged on a fixing structure of the intelligent magic cube. The fixed knot of intelligence magic cube constructs including core 31 and with the relative static structure of core 31, this fixed knot constructs can not rotate in step along with the rotation on magic cube layer.

The rotation signal of the first cube layer 41 refers to the position information of the first cube layer 41 after rotation, or the rotation direction and rotation angle of the first cube layer 41 (which is combined with the initial position, and the position information of the first cube layer 41 after rotation can be obtained as well). Similarly, the rotation signal of the second cube layer 42 refers to the position information of the second cube layer 42 after rotation, or the rotation direction and rotation angle of the second cube layer 42.

There are many specific configurations of the sensor 10.

For example, in conjunction with fig. 2 and 3, the first rotor 210 or the second rotor 220 is an electrically conductive member 230. The conductive member 230 includes a first contact pin 231 and a second contact pin 232. Accordingly, the stator 100 is provided with a common signal ring 103 and an angle signal ring 104 insulated from the common signal ring 103. Optionally, the common signal ring 103 and the angle signal ring 104 are coaxial. The first contact pin 231 is for contacting the common signal ring 103 and the second contact pin 232 is for contacting a different position of the angle signal ring 104. When the first magic cube layer 41 or the second magic cube layer 42 rotates, the first electric shock pins 231 are always pressed with the common signal ring 103 and keep relative sliding contact. The second contact pin 232 is always pressed against the angle signal ring 104 and keeps a relative sliding contact. The position of the conductive member 230 is changed, so that the connection relationship between the common signal ring 103 and the angle signal ring 104 is changed, and thus different signals, i.e., rotation signals of the first or second cube layer 41 or 42, can be generated.

Further, the angle signal ring 104 includes a plurality of sub-electrodes circumferentially spaced apart. Stator 100 also includes a resistor assembly. The common signal ring 103, the angle signal ring 104 and the resistor component cooperate to form a plurality of acquisition paths with different resistance values. The acquisition paths are in one-to-one correspondence with the sub-electrodes. A resistor, a sub-electrode and a common signal ring 103 are connected to each acquisition path. The conductive member 230 rotates to turn on the different sub-electrodes and the common signal ring 103, thereby turning on the different acquisition paths. According to the difference of the resistance values of the acquisition paths, the rotation signal of the first magic cube layer 41 is acquired.

For example, the first rotor or the second rotor is a plurality of magnets, and the magnetic field strengths of the respective magnets are different from each other. Correspondingly, the stator is a magneto-sensitive sensor. The magneto-sensitive sensor can be selected from Hall sensor, magneto-sensitive diode, magneto-sensitive resistor or application specific integrated circuit. When the first magic cube layer or the second magic cube layer rotates, different voltages are generated when the magneto-sensitive sensing device passes through different magnets. And acquiring rotation signals of the first magic cube layer or the second magic cube layer according to different voltages.

For another example, the first rotor or the second rotor comprises a light source and a baffle plate arranged below the light source, and the baffle plate is provided with a notch. Accordingly, the stator is a plurality of light receivers. When the baffle rotates along with the first magic cube layer or the second magic cube layer, the notch rotates to align different light receivers, and then the light receiver can receive the light of the light source, acquires the rotation signal of the first magic cube layer or the second magic cube layer.

Specifically, referring to fig. 1 to 3, the stator 100 includes a first induction plate 110, a second induction plate 120, and a fixing base 130. The first sensing plate 110 and the second sensing plate 120 are respectively and fixedly mounted on two sides of the fixing base 130. The first sensing plate 110 is used for sensing a rotation signal of the first rotor 210, so that the first sensing plate 110 can acquire the rotation signal of the first magic cube layer 41. The second sensing plate 120 is used for sensing a rotation signal of the second rotor 220, so that the second sensing plate 120 can acquire the rotation signal of the second magic cube layer 42.

The first rotor 210, the first sensing plate 110, the fixing base 130, the second sensing plate 120, and the second rotor 220 are sequentially disposed. The first sensing plate 110 and the second sensing plate 120 are fixedly mounted through the fixing base 130. The first sensing plate 110 and the second sensing plate 120 are respectively matched with the corresponding rotors, so that the structure of the whole sensor 10 is simpler and more orderly. The first sensing board 110 and the second sensing board 120 can be selected as circuit boards, wiring can be performed on the circuit boards according to actual needs, a plurality of signal wires are not required to be led out, wiring and assembly errors are reduced, the sensor 10 is simple and compact in circuit, and batch production is facilitated.

Further, referring to fig. 1 to 3, a first signal lead-out end is disposed on a side of the first sensing plate 110 close to the fixed seat 130, a first sensing surface 111 is disposed on a side of the first sensing plate 110 far from the fixed seat 130, and the first sensing surface 111 is used for sensing a rotation signal of the first rotor 210; and/or, a second signal leading-out end 121 is arranged on one side of the second sensing plate 120 close to the fixed seat 130, and a second sensing surface is arranged on one side of the second sensing plate 120 far away from the fixed seat 130, and the second sensing surface is used for sensing a rotation signal of the second rotor 220.

The first signal extraction end and the second signal extraction end 121 are respectively connected to the wires 105, and send rotation signals of the first magic cube layer 41 and the second magic cube layer 42 to the main control module 21. Compared with the situation that the first sensing surface 111 and the first signal lead-out terminal are located on the same side of the first sensing plate 110, in this embodiment, the first sensing surface 111 and the first signal lead-out terminal are located on different sides of the first sensing plate 110, and the two side area positions of the first sensing plate 110 are fully utilized, the volume of the first sensing plate 110 can be designed to be smaller, correspondingly, the first rotor 210 in running fit with the first sensing plate 110, and the whole sensor 10 can also be designed to be smaller. Similarly, the volume of the second sensing plate 120 can be designed to be smaller.

In addition, since the first sensing plate 110 is miniaturized, the circumference thereof is shortened, the mating area of the first rotor 210 and the first sensing surface 111 is also reduced, the damage of the first rotor 210 is reduced, and the weight and inertia of the first sensing plate 110 are easily reduced. For example, when the first rotor 210 is the conductive member 230 including the first contact pin 231 and the second contact pin 232, the first sensing surface 111 includes the common signal ring 103 and the angle signal ring 104 located at the outer edge of the common signal ring 103, and the diameter of the first sensing surface 111 is reduced, so that the rotation path length of the first contact pin 231 and the second contact pin 232 is reduced, the abrasion amount of the first rotor 210 is greatly reduced, thereby improving the service lives of the stator 100 and the first rotor 210, and improving the life and reliability of the sensor 10. Similarly, the second sensing plate 120 is miniaturized, which is advantageous in reducing the wear amount of the second rotor 220.

Further, referring to fig. 2 and 3, the fixing base 130 is provided with a first mounting cavity 131, and the first mounting cavity 131 is used for mounting and fixing the first sensing plate 110; and/or, the fixing base 130 is provided with a second mounting cavity 132, and the second mounting cavity 132 is used for mounting and fixing the second sensing plate 120. The first installation cavity 131 and the second installation cavity 132 can avoid the interference of the first sensing plate 110 and the second sensing plate 120 by the environment or other components, especially in the intelligent magic cube with narrow internal space, multiple components and continuously rotating components during use.

Specifically, in conjunction with fig. 2, 3 and 5, the sensor 10 further includes a movable mount 240. The movable seat 240 is provided with a receiving chamber 241 at a side facing the stator 100. When the movable seat 240 is used for being connected with the first magic cube layer 41, the first rotor 210 is fixedly installed in the accommodating cavity 241, so that the first rotor 210 synchronously rotates with the first magic cube layer 41 through the movable seat 240. When the movable seat 240 is used for being connected with the second magic cube layer 42, the second rotor 220 is fixedly installed in the accommodating cavity 241, so that the second rotor 220 can synchronously rotate along with the second magic cube layer 42 through the movable seat 240. The accommodating cavity 241 can prevent the first rotor 210 and the second rotor 220 from being interfered, vibrated and impacted by the environment or other components, especially in the intelligent magic cube with narrow internal space, multiple components and continuously rotating components during use, so that the reliability and accuracy of detection cooperation among the first rotor 210, the second rotor 220 and the stator 100 are improved.

By converting the relative positional accuracy design between the first rotor 210 or the second rotor 220 with respect to the stator 100 into the relative positional accuracy design between the movable base 240 with respect to the fixed base 130, the precision is easier to design and secure, and is technically easier to implement and control. Optionally, the first rotor 210, the second rotor 220 and the movable seat 240 are fixedly connected by clamping, bonding or integrally forming.

Specifically, the movable mount 240 and the fixed mount 130 are coupled to each other. For example, referring to fig. 2, the movable seat 240 is sleeved on the fixed seat 130, so that the first rotor 210 and the second rotor 220 are in rotating fit with the stator 100 in a relatively closed cavity, and external interference is avoided.

Example two

The second embodiment differs from the first embodiment in that the specific structure of the stator 100 is different.

In the present embodiment, referring to fig. 12 to 14, one side of the stator 100 is provided with a first sensing part 140 for sensing a rotation signal of the first rotor 210, and the other side is provided with a second sensing part 150 for sensing a rotation signal of the second rotor 220. The first rotor 210 cooperates with the first sensing part 140 to output a rotation signal of the first cube layer 41. The second rotor 220 cooperates with the second sensing part 150 to output a rotation signal of the second cube layer 42.

Specifically, the first sensing part 140 and/or the second sensing part 150 includes a coil 101 and a sensing ring 102, the sensing ring 102 is used to sense a rotation signal of the first rotor 210 or the second rotor 220, and the coil 101 is provided with a terminal for outputting the rotation signal. The coil 101 can be electrically connected to the main control module 21 located in the core 31 through the wire 105, thereby transmitting rotation signals of the first and second cube layers 41 and 42 to the main control module 21.
